MILAN--(BUSINESS WIRE)--Sep 10, 2022--
Concert Pharmaceuticals, Inc. (NASDAQ: CNCE) today announced the presentation of data from its Phase 3 clinical trial, THRIVE-AA1. The presentation highlights THRIVE-AA1 study results evaluating Concert’s oral investigational medicine CTP-543 in adult patients with moderate to severe alopecia areata, an autoimmune disorder that results in patchy or complete scalp hair loss. The THRIVE-AA1 data are being presented by Brett King, M.D., Department of Dermatology, Yale University School of Medicine and clinical investigator of THRIVE-AA1, during the 31 st European Academy of Dermatology and Venereology (EADV) Congress Late Breaking News Session.
In the THRIVE-AA1 study, significant improvements in scalp hair regrowth compared to placebo were achieved at 24 weeks for patients taking 8 mg twice-daily and 12 mg twice-daily doses of CTP-543, as previously disclosed in the positive topline results reported by Concert earlier this year. Treatment with CTP-543 was generally well tolerated. The EADV presentation includes new data from the THRIVE‑AA1 study showing the ability of CTP-543 to achieve more stringent criteria for hair regrowth than the study’s primary endpoint of absolute Severity of Alopecia Tool (SALT) score of 20 or less (meaning 20 percent or less scalp hair loss) at Week 24. Specifically, 21 percent and 35 percent of the patients in the CTP-543 8 mg twice-daily and 12 mg twice-daily dose groups, respectively, achieved a SALT score of 10 or less at Week 24, compared to 0 percent of patients in the placebo group (p<0.0001). Also, the relative change in SALT score from baseline was significantly different for the 12 mg twice-daily dose group compared to placebo (p<0.001) as early as Week 4. In addition, new data are presented showing that patients in the THRIVE-AA1 study with loss of eyebrow or eyelash hair at baseline treated with CTP-543 had significant improvement compared to placebo over the 24-week treatment period (p<0.001).
“In the Phase 3 results to date, CTP-543 has hit the mark with the primary endpoint of SALT score of 20 or less, which is clinically meaningful scalp hair regrowth for patients with alopecia areata. It is notable that the majority of patients who achieve the primary endpoint achieve the more stringent endpoint of SALT score of 10 or less in the THRIVE‑AA1 study,” stated Dr. King. “These data are highly encouraging and support the potential of CTP-543 to regrow hair on the scalp, eyebrows and eyelashes in patients with alopecia areata, and in many cases with a rapid onset of effect.”
“Based on the strength of the THRIVE-AA clinical program data, CTP-543 has the potential to be a best-in-class treatment for alopecia areata,” stated James V. Cassella, Ph.D., Chief Development Officer at Concert Pharmaceuticals. “Alopecia areata is a serious autoimmune disorder that has a strong association with emotional and psychosocial impact on patients’ lives. We hope that CTP-543 has the potential to bring broader benefit to alopecia areata patients and plan to file a New Drug Application for CTP-543 in the first half of 2023.”
The Phase 3 data presented at EAVD include a comprehensive review of the THRIVE-AA1 results and are consistent with the topline data reported in May 2022 by Concert:
Details from the oral presentation, entitled “Top-Line Results from THRIVE-AA1: A Phase 3 Clinical Trial of CTP-543 (deuruxolitinib), an Oral JAK Inhibitor, in Adult Patients With Moderate to Severe Alopecia Areata,” is available in the Scientific Presentations section of Concert’s website.
About THRIVE-AA1
THRIVE-AA1 (NCT04518995) was a randomized, double-blind, placebo-controlled clinical trial in 706 adult patients age 18-65 with moderate to severe alopecia areata at sites in the U.S., Canada and Europe evaluating the regrowth of scalp hair after 24 weeks of dosing using the SALT score. Patients were randomized to receive either 8 mg twice-daily or 12 mg twice-daily of CTP-543 or placebo for 24 weeks. The primary endpoint was the percentage of patients achieving a SALT score of 20 or less at 24 weeks.
Patients enrolled in THRIVE-AA1 were required to have at least 50 percent scalp hair loss due to alopecia areata, as measured by SALT. A SALT score of 100 represents total scalp hair loss, whereas a score of 0 represents no scalp hair loss. The average baseline SALT score across all patients in THRIVE-AA1 was approximately 85.9 (corresponding to less than 15% average scalp hair coverage).
All patients who completed 24 weeks of treatment in THRIVE-AA1 had the opportunity to continue in a separate extension study to evaluate long-term safety and efficacy of CTP-543. More than 95% of eligible patients in THRIVE-AA1 elected to roll into the extension study.
About CTP-543 and Alopecia Areata
CTP-543 is an investigational oral selective inhibitor of Janus kinases JAK1 and JAK2. The FDA has granted CTP-543 Breakthrough Therapy designation for the treatment of adult patients with moderate to severe alopecia areata and Fast Track designation for the treatment of alopecia areata.
Alopecia areata is an autoimmune disease in which the immune system attacks hair follicles, resulting in partial or complete loss of hair on the scalp and body. Alopecia areata may affect up to approximately 1.5 million Americans at any given time. 1 The scalp is the most commonly affected area, but any hair-bearing site can be affected alone or together with the scalp. Onset of the disease can occur throughout life and affects both women and men. Alopecia areata can be associated with serious psychological consequences, including anxiety and depression. There are currently limited treatment options available for alopecia areata.
About Concert
Concert Pharmaceuticals is a late-stage clinical biopharmaceutical company that is developing CTP-543, a novel oral JAK1/2 inhibitor. Concert has successfully completed two Phase 3 trials with CTP-543 in adults with alopecia areata, a serious autoimmune dermatological condition. The Company is also evaluating the use of CTP-543 in other indications and assessing a number of earlier-stage pipeline candidates.
